When a hot water system goes, it tends to do so very suddenly. So if you’re about due for a replacement, then you’re best of looking into the different options now, without the stress of having no hot water (unless you love having cold showers!). Water heating can account for a quarter of typical household energy use, so it’s worth reviewing your household’s hot water usage long before your current system goes and researching the alternatives – you may find a system that saves energy, money and is kinder to the environment. Supaflow Plumbing specialise in hot water heater repairs and installations – and can recommend the best hot water heaters available if you need advice.

Hot Water Heater Buying Guide (there are 2 main types):

This type only heats as much water as you need, when you need it – meaning you’ll never have to put up with a cold shower again! If you turn on the tap, cold water will flow through a heat exchanger, igniting a gas burner or switching on an electric element. Another advantage to installing an instantaneous hot water heater is that the heater no longer has to heat and re-heat water in a tank like a conventional hot water heater. Having an instantaneous hot water heater means you will have an ‘endless’ supply of hot water in your home. The size you need (the flow-rate in litres per minute) depends on the number of hot water outlets the heater has to serve, more than the number of people in the household. As a general rule, for a two-bathroom house you need a flow-rate of about 22-24 L/min. Talk with one of our friendly team members or your supplier for advice on working out the best capacity for your situation.

Electric instantaneous hot water heaters
These models have to be connected to the day-rate tariff, so the running costs will probably be higher than with an off-peak storage system. However, they’re still cheaper to run than day-rate storage heaters due to the fact that there is no tank to lose heat. It is important to note that new models have better temperature control than older ones you may have come across.

Gas instantaneous hot water heaters

As opposed to older models, modern systems now have an electronic control that ensures a constant temperature up to the model’s maximum flow-rate. You can select different temperatures for different water outlets - 55 degrees celsius in the kitchen and laundry for instance, and 40 degrees celsius in the bathroom (to avoid the risk of scalding).

Standard models have a pilot light, which wastes a certain amount of gas, making models with electric ignition more economical. Gas instantaneous heaters can be installed externally, or internally with a flue. They’re also cheaper to run than gas storage systems due to there being not heat tank loss.

The water in this type of hot water heater is heated to a relatively high set temperature (usually between 60 degrees celsius and 70 degrees celsius) and kept ready for use in the tank. When you use hot water, it’s drawn from the top of the tank and replaced by a layer of cold water at the bottom. The temperature drop is sensed by a thermostat, which turns on the heater at the bottom of the tank. Although the tank is insulated, it’s constantly losing energy, meaning the water temperature drops over time unless it’s re-heated. If you draw off hot water faster than the cold water can be heated up, the cold layer will eventually move to the top of the tank and you’ll run out of hot water.
